join 2 mpg files without rendering

Hi, I made an mpg in adobe premiere to put on my dvd. but now the problem is, The last minute of the vid ,after second try 6 hours rendering!!, gave an error. so now instead of just rerendering the movie with the possible chance it will give an other error I just want to render the last minute, now is my question with what I can do this the best and fastest way? can it be done in premiere?

thanks for the time, don't know if this tread was open somewhere else but I didn't know how to find the correct searchkey..
